Need a BIS Number in Belgium? Apply Online Through EU Process
If you’re working, studying, or handling official matters in Belgium but are not registered as a resident, you may need a BIS Number (Belgian Identification Number for Social Security).
A BIS Number is required for:
Foreign entrepreneurs, business owners who want to start businesses in Belgium, and students and professionals requiring registration for official purposes.
Employment and payroll
Taxes and social security
Healthcare and insurance
Administrative registrations
The good news? You can apply digitally through EU Process in just a few steps:
Prepare your documents:
Passport
ID Card (if applicable)
Passport photo
Proof of address (rental agreement, utility bill, bank statement, etc.)
Fill out the online form with your personal details and purpose for applying.
Confirm and consent: Understand that a BIS number is not a visa or residence permit — it is only an identification number.
